ONE MATERIAL.
INFINITE POTENTIAL.
Innovation at the intersection of nature and engineering.
What is TerraTech™?
TerraTech™ is our patent-pending monomaterial technology, empowering cellulosic textiles to reach their full potential by adding performance without fossil fuels.
It is durable, windproof, water-repellent, breathable and free from petrochemicals.
TerraTech™ is FreyZein’s innovative monomaterial multilayer, composed of three layers:
Cellulosic shell fabric
FreyZein’s groundbreaking cellulosic membrane (TerraMbrne™) and PFC-free DWR (TerraShield™)
Cellulosic backing
TerraMbrne™ is an eloctrospun membrane made from 100% cellulose.
It can be engineered to be hydrophobic (water-repellent) or hydrophilic (absorbent).
TerraShield™ is FreyZein’s PFC-free durable water-repellent finish (DWR), adding superior hydrophobicity to our products.
HIGH-PERFORMANCE, ENGINEERED BY NATURE.
At the core of TerraTech™ is a 100% cellulose membrane, bonded with natural layers.
By re-engineering nature’s building blocks, we unlock windproofness, water-repellency, and durability without plastics.
Windproof + water-repellent membrane
Cellulosic shell and backing for structure + comfort
100% free from microplastics

ONGOING R&D.
We steadily challenge ourselves to constantly improve and keep pushing the boundaries of what’s possible, with sustainability in mind.
Our mission to shift the textile industry away from petrochemicals led us to explore different types of thermal insulation, crucial for performance in cold temperatures.
Introducing TerraDown™
TerraDown™ is an innovative, Aerocellulose-infused thermal insulation material. FreyZeins® cutting-edge technology delivers a 100% cellulose-based multilayer nonwoven structure engineered for extreme performance.
TerraDown™ combines exceptional thermal insulation properties with flexibility, breathability, and resistance to water retention at a fraction of the weight and thickness of traditional solutions.
